I like it. The fact that it's so true, as you say, improves the poem. Your emotion is in this piece and around it. You made me believe you. Good job. And I am guessing the meaning, but leaving it unsaid.

One piece of criticism. . .Except isn't a very good poetry word, in my humble opinion. I believe "only" would work well there, or "yet". But that's just me:)

All around, a great piece of work, and the fact that you're talking about something embarrasses you increases the goodness. Keep it up.
